THILL-COUPLING.

QPECIIICATION forming part of Letters Patent No. 300,750, dated June 24, 1884.

Application iiled August 24, 1883. (No model.)

To all whom, it may concern.-

Beit known that I, EDWARD I. ALEXAN- DER, of Clinton, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Anti-Rattlers for rPhill-Couplings; and I do herebydeclare the following to be a full, clear, and exact descriptiouof the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification,

My invention relates to an improvement in anti-rattlers for chill-couplings; and it consists, first, in the combination of a thill-coupling with a spring that is adapted to have one end secured to the clip, and its free end to bear against the barrel ofthe draft-iron; second, in the combination, with a shaft-coupling of any desired construction, of an arm that is adapted to besecured to one end of the coupling-bolt, and a spring that is secured to the arm, the upper end of which spring bears v against the barrel of the-draft-ircn, and thus ArO effectually prevents the rattling of the coupling, as will be more fully set forth'hereinafter.

In the accompanying drawings, Figure lis a side elevation of a device embodying my in-V is a cross-section ofthe same Figs. 3 and 4 are vention. Fig.2 on the lin'e a: x of Fig. 1. detailed perspectives.

A represents an ordinary clip having the cars B, between which ears the barrel C or" the draft-iron D is secured by means of the coupling-bolt E.

F represents an arm, which has its lower end, Gr, bent at right angles, .and which is provided with an opening, G', in its upper end, for the coupling-bolt E, and a screwthreaded opening, G2, in its inner bent end Vfor the screw I.

II represents a spring, which is preferably of the shape shown in Figs. 1 and 3, but which may be of any suitable form. The

lower straight end II of this spring is sethe bent portion G- of the arm F by I, which passes through and through cured to means of the screw a an opening formed in the spring,

Gr2 of the arm. The upper end the opening against the barrel of Anot normally pressed tightly against the under side oi' the bent end of the arm, but is secured at a slight angle thereto, thus allowing for greater compression to be applied to the barrel by tightening the screw I. This causes the spring II to bear only against one side ofthe enlarged head of the screw I, and exerts a side pressure on the screw, which effectually prevents it from working loose.

Heretoi'ore springs have been placed immediately between the clip and the barrel of the draft-iron, and have also been formed as an extension of the clip-tie; but all such devices necessitate the use of a clamp in order to bring the draft-iron back into place between the ears in position to have a couplingbolt passed through it, but by having an arm which is adapted to be placed upon 'the end of the coupling-bolt, and by having a spring secured to the arm, I am' enabled to apply my anti-rattler to a -thill-coupling of any ordinary construction Without the use of any clamping mechanism whatever, and thus effect not only a saving of labor, but a saving of time. Moreover, the spring H, upon being compressed against the barrel of the draft-iron, exerts a lateral pressure upon the arm F, which causes the arm to pinch unevenly against the nut K, and thus acts as a lock to keep the nut in position upon the coupling-bolt. y

I do not desire to limit myself to the precise construction hereinbefore described, as it is obvious that many modifications may be made therein without departing from the spirit of my invention.

' Having thus described my invention, I claim- 1. rIhe combination of a clip, a draft-iron secured therein, arm F, and spring II, secured to said arm,and having its free end bearing against the barrel of the draft-iron, substantially as shown and described.

2. The combination ofthe clip A, draft-'n iron D, cou'pling-b01t E, arm F, secured to binecl and :urau said bolt at one end, spring H, and screw I, as described. substantially as set forth.
